My manu lost in last important game

I still cannot believe the last game result, Manchester United lost to Chelsea in their home. In score table, manu is still the number one by having better goal difference than blue, but the score advantage is no more. One of major cause of the lost, in my view is the manager Ferguson holding up some major strikers like C. Ronaldo to reserve the power for next important match versus Barcelona. Why Ferguson did not plan a full team to get the victory in that important match. The suitation is much more worst now. In order to become dual champions, manu will need to WIN all the remaining matches. Dual champions road is tough. As of manu fans, I still believe manu can finish this impossible mission.
